Abstract:
Provided are a polymer and a polymer actuator including the polymer. The polymer is cross-linked by a cross-linking agent. When the polymer is used in the polymer actuator, the polymer actuator shows a high strain and may be stably operated at high temperatures.
Abstract:
A large-area transmissive type optical image modulator, a method of manufacturing the same, and an optical apparatus including the transmissive type optical image modulator are provided. The large-area transmissive type optical image modulator includes: a base substrate; a first expitaxial layer formed on the base substrate; a second expitaxial layer formed on the first expitaxial layer; a first electrode formed on the first expitaxial layer and spaced apart from the second expitaxial layer; a second electrode formed on the second expitaxial layer; and a transparent substrate covering the second expitaxial layer and the second electrode, wherein the base substrate includes a through hole corresponding to a light emitting area, and the first expitaxial layer may include an n-type or p-type doping material.
Abstract:
An infrared transmission large-area shutter is provided. The infrared transmission large-area shutter includes a first contact layer on a substrate, a plurality of stacks formed in a two-dimensional (2D) array pattern on a first region of the first contact layer, each stack comprising a lower reflection layer, an active layer, an upper reflection layer, and a second contact layer which are formed sequentially in this order on the first contact layer, a first electrode formed on the first contact layer, a plurality of second electrodes on the second contact layers, a first polymer layer that surrounds sidewalls of the plurality of stacks on the first contact layer, and a second polymer layer, which is transparent to infrared rays, to cover the second electrode on the second contact layer. A through hole corresponding to the plurality of stacks is formed in the substrate.
